Azazel, the goat that escapes cannot be Yeshua, because Yeshua died as the substitutionary sacrifice for Israel. The goat that dies at Yom Kippur is named "For HaShem", and not "Azazel". Therefore, Azazel must represent something else. The text of the Scripture is clear, it tells us that the goat that escapes is identified by the High Priest as being the goat that is named for the sin of Israel. Azazel is Israel, her redemption both individual and corporate is purchased by the goat named "For HaShem": it is this goat that is a figure for the Messiah Yeshua.

Great to identify the goats are presented as one sacrifice. One is chosen by Hashem, the other gets to escape. As you say, like Issac escaping his life under the knife of Abraham, because YHVH provided a goat in the thickets. Likewise the Lamb of God shed his pure blood, a covering atonement in place of all those who deserve just punishment. Therefore, those who believe (put their entire trust in as Lord and Master of their lives) escape the penalty of sin. Blessed be our Jewish Husband, Yeshua, the Messiah!
